JavaScript / Fetch

For a genuinely dependency-free environment only. If npm is available, prefer Node.js or a framework adapter instead — @raykoi/sdk’s client.form(id).submit() already does this internally, plus CAPTCHA, retries, and idempotency.

const response = await fetch(
  "https://api.raykoi.com/api/v1/submit/p/YOUR_PUBLIC_ID",
  {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({
      data: { email: "user@example.com", name: "Alice" }
    })
  }
);

const result = await response.json();
